IMPnmiEMBNT IN DRIVING-BELTS.

TO ALL WHOM IT MAY CONCERN-1 Be it known that we, T. B WmTEn-nd W. G.BEDFoRD, ofPhiladelphia, Pennsylvania, have invented an 'll clear;-eiildekeot description ot' the' improved- Driving-Belt and we do herebydeclare the following .to be t v of reference marked thereon.

some, reference being had to the accompanying drawing. end to thelettieOur invention consists of it driving-belt composed of wires, bent '01;corrugated, as described hereafterj'and interwoven with threads orstrands of cotton, hemp, jute, oakum, or other fibrous materiel thebelt'thus manufac-tu 'cd being more efiicient thanbelts composed of wireand threads heretofore made} I in order to enable others to malt-e our.inventionnre will now proceed to describe the manner in which it may beconstructed. On reference to the accompanying drawing whieh forms a,part of this specification- Figure 1 represents a portion of ourimproved driving-belti v '1 I Figure 2 a section of the same drawn to anenlarged scale; and Figure 31st. sectionon the line 1-2, fig. 2. v I i,7 r A represents the warp, composedof ordinary wire, whieh iscorrugated or bent; as sh;own,en.d B eportion of the belt, completed byinterweaving \vitlrthefwarp wires, threiids or strands of cotton, hemp}.jute; oakumybr other fibrous material. The wezrvmg of this fabric mayberapidly accomplished in a. loonrdiii'ering butlittlej from those ofordinary constrnction, thewrire being corrugated in the loonrprevious'tointerweaving the thread Experiments have proved that driving-belts thusmade are most'effieient and of great strengthrand they improve bycontinued use, owing to the surface becoming gradually smooth 'bycontact with the pulleys f while the corrugations in the w'ire preventthe weft threads from slippingon the wires, as'oceurs when thethreadsare woven with straight wires in the ordinary inenncr. l

By ni'aking the wires ateach edge somewhat thicker and stronger thanthose in the middle the quality the belt isimproved; V I H That side ofthe beltin contact with the pulleys may be coated with gumi elastic orgutter percha, or may be coated with water-proof varnish or paint, andthe wires may be clothed with threeds of any suitable fibrous inaterial, by braiding or otherwise, prior to being interwoven with theWeft threads.

3 We elaim a sour invention, and desireto secure by Letters Patent as a.new manufa. cture- "A driving-belt composed of tires, corrugated or.bent, as described, and threads of cotton or other fibrous hu teriail'interwoven as set; forth;
